This study is a real world experience comparing liver iron concentration (LIC) estimation by R2* vs R2 method in 107 patients with hemoglobinopathies on chronic transfusion therapy. It demonstrates a strong correlation of R2* with R2 and furthermore highlights the advantageous short scan time of R2* in the pediatric age group.
